As shown in fig. 1-2, the embodiment provides a high-temperature and high-pressure geothermal well open flow test device, which comprises a vapor-liquid separation tank 1, a vapor-liquid separation tank 2 and a vapor-liquid mixture main pipe 3, wherein the volume of the vapor-liquid separation tank 1 is larger than that of the vapor-liquid separation tank 2. The inlet end of the gas-liquid mixture main pipe 3 is used for connecting a high-temperature high-pressure geothermal well mouth, the outlet end of the gas-liquid mixture main pipe 3 is respectively connected with the inlet of the tank body mixture inlet pipe 4 and the inlet of the tank body mixture inlet pipe 5, the outlet of the tank body mixture inlet pipe 4 is positioned above the inside of the gas-liquid separation tank 1, and the outlet of the tank body mixture inlet pipe 5 is positioned above the inside of the gas-liquid separation tank 2. And, all be equipped with a high temperature high pressure valve on vapour-liquid mixture house steward 3, box mixture advance pipe 4 and the jar body mixture advance pipe 5, through opening or closing of each high temperature high pressure valve, thus can control the circulation and the flow direction of mixture.
The upper end of one side of the gas-liquid separation tank 1, which is far away from the tank mixture inlet pipe 5, is connected with a plurality of tank steam exhaust pipes 6, and each tank steam exhaust pipe 6 is provided with a tank steam measurement component which is used for monitoring relevant parameters of steam flowing out of the gas-liquid separation tank 1. The lower end of one side of the gas-liquid separation tank 1, which is far away from the tank mixture inlet pipe 4, is connected with a tank liquid discharge pipe 7, the outlet end of the tank liquid discharge pipe 7 can be connected with a triangular weir box, a tank liquid measurement component is arranged on the tank liquid discharge pipe 7, and the tank liquid measurement component is used for monitoring relevant parameters of liquid flowing out from the gas-liquid separation tank 1.
Similarly, the upper end of one side, far away from the box mixture inlet pipe 4, of the vapor-liquid separation tank 2 is connected with a tank vapor discharge pipe 8, and the tank vapor discharge pipe 8 is provided with a tank vapor measurement component which is used for monitoring related parameters of vapor flowing out of the vapor-liquid separation tank 2. The lower end of one side of the gas-liquid separation tank 2 far away from the tank body mixture inlet pipe 5 is connected with a tank body liquid discharge pipe 9, the outlet end of the tank body liquid discharge pipe 9 can be connected with a triangular weir box, a tank body liquid measurement component is arranged on the tank body liquid discharge pipe 9 and is used for monitoring relevant parameters of liquid flowing out from the gas-liquid separation tank 2.
In addition, a manifold fluid monitoring assembly can also be arranged on the gas-liquid mixture manifold 3 for detecting relevant parameters of the fluid in the gas-liquid mixture manifold 3.
In the actual use process, the mixture blown out by the high-temperature high-pressure geothermal well is sprayed into the gas-liquid mixture main pipe 3 through a pipeline, then flows into the box mixture inlet pipe 4 and the tank mixture inlet pipe 5 respectively from the gas-liquid mixture main pipe 3, flows into the gas-liquid separation box 1 and the gas-liquid separation tank 2 respectively through the box mixture inlet pipe 4 and the tank mixture inlet pipe 5, and performs gas-liquid separation operation. The gas separated in the gas-liquid separation box 1 is discharged through a box steam discharge pipe 6, and related data detection is carried out by a box gas measurement assembly; the liquid separated in the vapor-liquid separation tank 1 is discharged through the tank drain pipe 7, and the tank liquid measuring assembly performs relevant data detection. Similarly, the gas separated in the gas-liquid separation tank 2 is discharged through a tank gas discharge pipe 8, and related data detection is carried out by a tank gas measurement assembly; the liquid separated in the vapor-liquid separation tank 2 is discharged through the tank drain pipe 9, and the relevant data detection is performed by the tank liquid measuring assembly. Thus, by double detection of the vapor-liquid separation tank 2 and the vapor-liquid separation tank 1, the detection accuracy can be improved.
When the flow rate in the gas-liquid mixture main pipe 3 is low, the box mixture inlet pipe 4 can be closed, the tank mixture inlet pipe 5 can be opened, and only the gas-liquid separation tank 2 is used for gas-liquid separation and detection. The reason is that if only a small amount of the mixture is used, once the mixture enters the vapor-liquid separation tank 1, the mixture may not flow out, so that the vapor-liquid separation tank 2 having a small volume is used.

The tank gas baffle 13 is provided with a plurality of tank liquid seepage holes, and gas liquefaction may exist in the gas above the tank gas baffle 13, so as to prevent liquefied liquid from accumulating on the tank gas baffle 13, thereby setting the tank liquid seepage holes and allowing the liquefied liquid to flow down from the tank liquid seepage holes.
The mixture flowing out of the tank mixture inlet pipe 4 will drop to the right side of the tank liquid baffle 14 first, and because the gas is lighter, the gas will flow from above the tank liquid baffle 14 to above the tank gas baffle 13 and finally flow from the tank gas exhaust pipe 6, and in this process, if some liquid is present in the gas, the gas will flow into the bottom of the gas-liquid separation tank 1 through the tank liquid seepage hole.

The liquid discharged from the outlet of the tank mixture inlet pipe 5 directly falls to the bottom of the vapor-liquid separation tank 2, and then flows out from the tank liquid discharge pipe 9. The gas flows to the upper part of the tank body liquid baffle 15 and then is discharged from the tank body steam discharge pipe 8, and part of the liquid carried in the gas also falls downwards due to the self weight of the liquid, and part of the liquid also passes through the tank body liquid seepage hole and falls downwards.
